I think, i got the solution by prestarting listen serverjobs and working with a data que. This reduces the runtime by factor 3. It's now similar like a common server box, maybe better - depending of the prestarted jobs. May a bottleneck, writing to the IFS. Could be prevented by SSD drives, but I don't know. Note: It's special to generate such a huge amount of jpg's and removing them also - only by a lack of non-overlay QR codes with images. Means, you can print a QR-Code and a try to overlay it with a pic - the pic will always remain in the background and will be overwritten with the QR-Code. (and I haven't even talked about colored QR codes yet) Karl -----Ursprüngliche Nachricht----- Von: JAVA400-L [mailto:java400-l-bounces-+hD5IHI5Xscn3HwCXmMcX9BPR1lH4CV8@public.gmane.org] Im Auftrag von D*B Gesendet: Montag, 30.

But it's still too slow! For 1000 QR Codes needs my i9 3 Min and the customer talks about 2 Million documents with a QR-Code. </Karl> I remember a similar discussion in a german forum and by phone... What is the exact requirement? 2 million should take how long?
